Materials Data on H5CN3O4 by Materials Project
CN3H5O4 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four CN3H5O4 clusters. C4+ is bonded in a trigonal planar geometry to two N+0.33- and one O2- atom. Both C–N bond lengths are 1.33 Å. The C–O bond length is 1.32 Å. There are three inequivalent N+0.33- sites. In the first N+0.33- site, N+0.33- is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.26 Å) and one longer (1.28 Å) N–O bond length. In the second N+0.33- site, N+0.33- is bonded in a trigonal planar geometry to one C4+ and two H1+ atoms. Both N–H bond lengths are 1.02 Å. In the third N+0.33- site, N+0.33- is bonded in a trigonal planar geometry to one C4+ and two H1+ atoms. There is one shorter (1.02 Å) and one longer (1.03 Å) N–H bond length. There are five inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.03 Å) and one longer (1.54 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N+0.33- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N+0.33- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one N+0.33- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one N+0.33- atom. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one N+0.33- and one H1+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one N+0.33- atom. In the third O2- site, O2- is bonded in a single-bond geometry to one N+0.33- atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one C4+ and one H1+ atom.
